Detailed Description

Class to enforce homogeneous neumann boundary conditions.

BoxGhostBC class implentation to enforce homogeneous neumann boundary conditions Recall that BoxGhostBC is a class to encapsulate the operations of ghost-cell boundary conditions at a face. If the solution is phi and the face normal direction is x, the boundary conditions usually used can be expressed as A*phi + B*dphi/dx = C. For homogeneous Neumann BCs, A=C=0, B= 1 These functions are only meant to be called by DomainGhostBC

Apply the inhomogeneous form of the boundary conditions to a_state along the boundary of a_domain.

virtual void ExtrapBC::fillBCValues FArrayBox a_neumfac,
FArrayBox a_dircfac,
FArrayBox a_inhmval,
Real  a_dx,
const ProblemDomain a_domain
const [protected, virtual]
 

Pure-virtual Worker function to fill arrays which define the boundary condition. Essentially, if the boundary condition is represented as A*phi + B*dphi/dn = C, then a_dircfac is A, a_neumfac is B, and a_inhmval is C.

Implements BoxGhostBC.

BoxGhostBC* ExtrapBC::new_boxghostbc  )  const [protected, virtual]
 

Virtual constructor workaround.
